Abstract: PURPOSE:To contrive to improve shock resistance at low temperature and to prevent barrier property from being lowered by using polyamide resin having the prescribed properties such as the tensile rupture elongation, bending modulus and permeability to gasoline for a polyamide layer. CONSTITUTION:The polyamide resin constituting a barrier layer must have at least 100% of tensile rupture elongation at -40 deg.C, at most 500kg/cm<2> of rigidity in absolute dry condition at 23 deg.C and at most 1X10<-5>g/m.hr (in absolute dry condition at 30 deg.C) of gasoline barrier property. These three conditions are all necessary. When even one of said conditions lacks, the multilayer blow plastic tank having excellent shock resistance and barrier property at low temperature may be not obtained. That is to say, even if the tank has at least 100% of tensile rupture elongation, at most 5000kg/cm<2> of rigidity and excellent shock resistance at low temperature, when the gasoline barrier property exceeds this range, the barrier property is reduced, and the content such as gasoline in the tank leaks outside, whereby practical obstacles occur.
